产品描述
Main features:
The design of optical system - new, the host has excellent optical properties and light and stray light, low noise, high reliability and stable metering accuracy.
Unique deuterium lamp and tungsten light source installation, automatic switching and automatic design for optimum position and work mode, the user operation and maintenance of instrument light source replacing more convenient, correct and safe.
- excellent software design and programming, the instrument has strong spectral data processing function: automatic measurement of spectral scanning, multi wavelength ( From 1 to 3. Determination of kinetic determination,), From 1 to 3 Curve fitting, From 1 to 4 Derivative spectrum, spectrum analysis and display print data.
The use of large screen Chinese window display, with good man-machine interface.
